Saturday's incident could be connected to an Angel rider found shot dead 40 miles outside of Laughlin.
The Angels and the Mongols have been feuding for years.
In the early 70's there was confrontation at a motorcycle swapmeet in Pasadena when memebers of the Mongols allegedly stole items from a vendor. The Angels "intervened".
Around '78-'79 Mongols robbed and killed an Angel courier in Northern California.
The Frameup incident happened next.
The Frameup was a motorcycle shop owned by the Mongols in the Los Angeles area. Around closing time one Saturday, a punctured 16x5.00 Harley wheel was brought in for repair. Since the shop would be closed Sunday and Monday, it would be fixed Tuesday. Around 2:00 A.M. an explosion levelled the shop and part of both neighboring buildings. The wheel was loaded with C-4 military high explosives. Two occupants of the shop were killed.
The Mongols dropped from sight for several years til a brawl at the Orange County motorcycle swapmeet in October last year.
